MACHINE FOR CUTTING VENEERS.

SBEGIFICATIONforming part of Letters Patent No. 433,511, dated August 5, 1890.

Application filed April l0, 1890. Serial No. 347,327. (No model.)

To all whom it may concern,.-

Be it known that I, HORATIO M. BROWN, a citizen of the United States, residing at Ansonia, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Machines for Cutting Veneers; and I do hereby declare the following to be a full, clear, and exact description cf the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the class of veneercutting machines in which the log is rotated and the cutter is fed forward as the operation proceeds, and has forits object to provide automatic stop mechanism whereby the feeding movement shall be stopped with absolute certainty at a predetermined time, thus avoiding the necessity of watching the machine closely.

With this end in view my invention consists in the novel construction and combination of parts, which I will first describe in detail, and then specifically set forth in claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of the entire machine, the legs being removed. Fig. 2 is a view, on an enlarged scale, showing the feeding and stopping mechanism in end elevation, the shafts being in section on the line x in Fig. l; Fig. 3, a side elevation and plan View of the locking-piece; Fig. 4, a plan view of the end of the machine at which the feeding and stopping mechanism is placed; Fig. 5, a sectional view on the line y y in Fig. 2, and Fig. 6 is an elevation of the hand-lever for operating the stoppingdisk detached. l

l denotes the bed, and 2 the shaft, to which power is applied by belts (not shown) running over pulleys 3. The logis carriedin the usual manner by two spindles 4, having at their inner ends the usual prongs 5 to engage the log. The outer ends of these spindles are threaded, as at G, and are adapted to be moved longitudinally to engage logs of any length within the capacity of the machine by suitable hand-wheels 7. These spindles are held by sleeves S, themselves supported in boxes 9 upon standards lO. The hand-wheels are rigidly secured to flanged threaded sleeves 1l,

the ianges of which are engaged by collars l2, threaded to engage the outer ends of the sleeves 8. The spindles and-sleeves 8 are connected together by grooves and keys. (Not shown.) Rotary motion is imparted to the sleeves and spindles by means of pinions 13 on shaft 2, engaging gears 14 on the sleeves.

l5 denotes a gear on sleeve S, meshing with a pinion 16 on a short shaft 17, which is supported in a suitable bracket 1S. These portions of the machine do not differ, essentially, from other machines of this class in general use. I have not, therefore, deemed it necessary to illustrate the details of construction, nor to refer to them otherwise than in this brief manner.

19 denotes the cutter; 20, the carrier therefor, and 2l slides running upon ways 22 at opposite ends of the machine, to which the ends of the carrier are rigidly secured. These ways are formed in heavy cross-pieces 22a, which are rigidly secured to the bed at opposite ends of the machine.

It will be noticed in Fig. 4 that I have illustrated another slide on the opposite side of the machine. This slideand its companion (not shown) are used to support another carrier provided with a heavy roller, which bears against the surface of the log in the act of cutting veneer. This roller, being in common use, I have not deemed to require illustration. The slides are fed inward simultaneously by shafts 23, provided with right and left threaded portions, (not shown,) which engage the carriers. Intermittent rotary motion is imparted to these shafts by means of beveled gears 24, engaged by beveled pinions 25 on the shaft 2G. These gears and pinions in practice I cover by hoods 25, to prevent the possibility of anything getting caught therein. Shaft 26 is provided with a feed-ratchet 27, which is engaged bypawls 28, carried by rock-arms extending lug or projection 33, the purpose of which will presently be explained. At the outer end of shaft 26.1 place a stopping-disk 34, the diameter of which is slightly greater than the diameter ot' the feed-ratchet, and the face of which is beveled on the inner edge, as at 35. This disk is left free to move longitudinally on the shaft, as will presently be more fully explained.

37 denotes a spring bearing against the outer face of the hub of disk 34 and acting to force said disk inward into contact with the feed-ratchet. The outer end of this spring bears against a nut 38 at the extreme outer end of the shaft.

39 denotes a locking-piece carried by an arm 40, projecting outward from a slide 41. This locking-piece is supported in a bracket 4G, the bracket being provided with a longitudinal recess inwhich vthe locking-piece slides and with a slot in its top, through which a pin 47 passes, this pin being fixed to the locking-piece and in practice engaging the outer end of arm 40. The construction of these parts will be clearly understood, it is thought, from Fig. 4 in connection with Fig. 2. Slide 41 is fastened to and is adapt-ed to move upon cross-piece 22a.

2 denotes a top plate covering a portion of the slide, and -43 bolts passing through the top plate and through slots (see dotted lines, Fig. 4) in the slide and engaging the crosspiece. At the inner end of the slide is an upwardly-extending lug 44, and at the outer end ahandle45,for convenience in movingit backward.

48 denotes a bracket upon one of the slides 2l, and 49 a bolt whose thread engages this bracket, the head of which is adapted to engage lug 44 at the inner end of slide 41.

50 denotes a groove in the hub of disk 34, which is adapted to be engaged vby lugs 5l, projecting inward from vthe opposite sides of an elongated opening 55 in alever 52. The lower end of this lever is adapted to engagea notch 53 in a bracket 54. The peculiarity of construction and operation of this lever is the readiness with which it may be detached froln disk 34 and entirely removed from the machine. It will be noticed (see Fig. (i) that lugs 51 are a sufficient distance above the lower end-of opening 55 to permit the lever tobe passed over the sleeve. It is then allowed to drop down to place, the lower end of the lever engaging notch 53 in the bracket and the lugs engaging groove 50 in the sleeve. To remove the lever again it is simply lifted, which disengages the lower end-of the lever from the notch, and also disengages the lugs from the groove in the sleeve and permits removal of the lever. It will be noticed (see Fig. 3) that the locking-piece is provided with wearing strips or plates 391. These strips may be made of any suitable material, although in practice I find rawhide preferable. These plates or strips are secured in place by pins or in any suitable manner, so as to be readily removable to permit the substitution of new ones when worn.

The operation of placing the log in position, rotating it, and feeding the cutter forward is the same as in other machines of this class, and therefore is not thought to require description in detail. In starting, slides 21, the carrier, and cutter will of course be at their extreme retracted position-that is, at their greatest distance from the spindles. In Fig. 4 one of the slides and a portion of the carrier and cutter are shown at an intermediate position. `Let us suppose that power has been applied' to the machine. To commence the operation of cutting a veneer, the operator places one hand upon lever 52 and moves it toward the left, as seen in Figs. 4

and 5, against the power of spring 37. NV-iththe other hand the operator graspshandle 45 and moves slide 41, arm 40, and the locking-piece backward to the position shown -in Fig. 4, the locking-piece entering between the feed-ratchet and stopping-disk 34, as clearly shown in Fig. 4. As the operation of cutting theveneer proceeds, the slide 2l, toward the front in Fig. 4, will move inward until the head of bolt 49 will engage lug 44 at the 'inner end of slide 41. The continued inward movement of slide 21 will cause slide 41, and with it the locking-piece, `to be moved inward-that is to say, toward the center of the machine. It will be seen from the drawings that but slight movement of slide 41 is re-v quired to remove the locking-piece from be- IOC tween the stoppin g-disk andthe feed-ratchet.

As soon as the'locking-piece is removed, spring 37 will force the stopping-disk inward intoY contact with the feed-ratchet. As the stopping-disk is Vmoved inward, projections 33 upon the feed-pawls will ride up bevel 35 upon the inner edge of the stopping-disk, so that said Vpawls will rest upon the periphery of the disk and entirely out of contact with the feed-ratchet, thus stopping the feed instantly. v

It will of course be understood that the parts are set by adjustment of lthe lockingpiece, or preferably by adjustment of bolt 49, so that the operation of cutting will continue just as 'far as possible without danger of the cuttercoming in contact with the prongs which hold the logs. At. the instant that the limit of safety for the inward movement of the cutter has been reached, the head of bolt 49 will have engaged lug 44 at the inner end of slide 41, and will have mo ved the locking-piece out from between the stopping-disk andthe feedratchet. It will be seen that this stopping mechanism wholly dispenses with the necessity for close watching of the machine, as not the slightest damage can happen'to the machine if it continues running after the feeding operation has been stopped.- Should it beV necessaryor desirable to stop the feeding operation at any time during the operation of cutting without stopping the entire machine', the operator simply has to push slide-4l back- IIO CSO

ward by means of handle 45 snfficientlyto withdraw the locking-piece from between the feedratchet and the stopping-disk. `As soon as the locking-piece has been removed, no matter whether the movement is performed automatically or by hand, spring 37 will force the stopping-disk into contact with the feedratchet and will lift the feed-pawls up out of contact with the ratchet.

The return movement of slides 21 and the cutter is effected by hand in anyordinary or preferred manner. In thedrawings (see Fig. l) I have shown a pinion 56, mounted in a suitable bracket 57, and provided with a crank 58 for convenience in operation. This pinion meshes with a pinion 59 at one end of shaft 2G, (the right,) as shown in the drawings, and by means of bevel-pinions 25 on said shaft and bevel-gears 24 on shafts 23 moves the slides, and with them the carrier and cutter, backward to the retracted position.

It will of course be understood that the various details of construction maybe varied to an almost unlimited extent without departing from the principle of my invention.

I claim- 1. The-combination, with the feed-ratchet, the shaft therefor, and the feed-pawls having projections 33, of a disk adapted to move longitudinally on the shaft, said disk being of greater diameter than the feed-ratchet and beveled upon its inner edge, s'o that when said disk is moved inward the feed-pawls will ride up the incline and rest upon the periphery of the disk wholly out of engagement with the feed-ratchet, thereby stopping the feed without stopping' the machine.

2. The combination, with the feed-ratchet, shaft, and pawls, the latter projecting over the edge of the ratchet, of a disk of greater diameter than the feed-ratchet and beveled upon its inner edge, said disk being adapted to move longitudinally on the shaft, and a spring acting to force the disk inward against the feed-ratchet, as and for the purpose set forth.

3. The combination, with the feed-ratchet, pawls, and shaft, said pawls projecting outward from the face of the ratchet, of a disk of greater diameter than the feed-ratchet, said disk being adapted to move longitudinally on the shaft and to lift the pawls out of contact with the ratchet. i

4. The combination, with the feed-ratchet, pawls, andshaft, said pawls projecting outward from the face of the ratchet, of a disk of greater diameter than the feed-ratchet, said disk being adapted to move longitudinally on the shaft and lift the pawls out of contact with the ratchet, a spring acting to force the disk inward, and a lever engaging the disk, whereby said disk may be forced outward against the power of the spring.

5. The combination, with the feed-ratchet, pawls, shaft, and bracket 54, having a notch at its outer end, of a disk of greater diameter than the feed-ratchet and having a groove 50 in its hub, the ratchet being adapted to slide longitudinally on the shaft, for the purpose Set forth, a lever having an opening to receive the hub of the disk, and lugs above the center of said opening adapted to engage the groove, the lower end of said lever being adapted to engage the notch in the bracket, so that said lever maybe attached or detached without movement of other parts.

6. The combination, with the shaft, bracket 54, having a notch 53, and disk 34, having a circular groove in its hub, of a lever provided with an elongated opening adapted to receive the hub of the disk, and inwardly-extending lugs in the upper portion of said opening, adapted to engage the groove in the disk, so that when the lever has been passed over the hub of the disk and the lower end seated in the notch the lugs will engage the groove, as and for the purpose set forth.

7. The combination, with the feed-ratchet, pawls; and shaft, of a disk adapted to move inward on said shaft to lift the pawls out of engagement with the feed-ratchet, and a locking-piece adapted to lie between the feedratchet and the disk to hold the latter out of contact with the pawls.
